When selecting a silicon carbide abrasive wheel, various factors must be taken into account, including material type, grit size and severity of grinding. Grain types that can be used include ceramic alumina, zirconia alumina, green silicon carbide and aluminum oxide. Each offers distinct performance characteristics: Alumina is suitable for steel and iron applications while green silicon carbide should be considered when working with non-ferrous materials or hard brittle workpieces. Hardness Silicon carbide is harder and brittler than aluminum oxide, making it ideal for grinding hard low-tensile strength materials like cast iron and non-metallic metals. Additionally, it may be used to grind fiberglass, medium density fiberboard and some plastics; however, this […]

砥石は、砥粒が結合した表面を持つ工具で、さまざまな材料を使用してワークピースから材料を除去します。砥石の種類と重要度によって、どの砥粒、砥粒の大きさ、砥粒の等級を使用するかが決まります。砥粒の結合は、ホイールの速度と寿命の両方に影響するため、極めて重要です。結合の違いにより、硬度レベルや破壊靭性レベルが異なります。砥粒 砥石を購入する際には、いくつかの特性を考慮する必要があります。砥粒の砥粒度、粒度、ボンド強度などです。砥粒の砥粒度は、材料を貫通して除去する能力を決定します。

炭化ケイ素は、一般的にはSiCの頭文字で呼ばれ、ケイ素と炭素からなる研磨材で、研磨材として19世紀後半から工業的に生産されている。さらに、SiCの天然鉱床はモアッサナイト鉱物層の中に存在する。セラミック釉薬にはこの物質の粉末が含まれており、セラミック窯の焼成に加えると、ガラスの気泡が発生し、視覚的・質感的に魅力が増します。炭化ケイ素は、材料を研磨する際のブラスト媒体として使用される非常に硬い物質で、モース硬度はダイヤモンドに近い。さらに、このセラミック材料は、研削砥石や切削工具の一部を形成するだけでなく、次のような製品にも使用されている。

Aluminum oxide and silicon carbide are among the most frequently chosen abrasives for blasting applications, offering various degrees of wear resistance and cost. Both options work efficiently when it comes to removing rust and paint, deburring metal, etching glass and more – but which one is the right one for your application? Black silicon carbide is an extremely hard man-made ceramic abrasive that ranks 9.1 on Mohs scale. Versatility Silicon carbide is a versatile abrasive that excels in many applications, particularly those where precise surface finishes are important, like aerospace or automotive industries. Furthermore, silicon carbide’s excellent cutting performance also plays a significant role in restoration work by helping remove

Aluminum oxide (Al2O3) is an affordable, versatile, and long-term blasting option, and works well on multiple materials such as metal and wood. Aluminum oxide comes in brown, white and pink variants to meet different levels of durability and create smoother finishes. White and pink variants deteriorate faster than brown varieties but work great with soft woods and metals. Hardness Silicon carbide (SiC) is a tough and long-wearing abrasive material available in varying grit sizes for polishing metals, glass, marble and wood surfaces; deburring rust removal; wood refinishing as well as wet sanding applications. Hard and sharp surfaces such as automotive surfaces benefit most from using these stones; their hardness and
